Hello R users I ran more than 100 logistic regression analyses. Some of the analyses gave me this kind warning below.
########################################################### Warning messages: 1: algorithm did not converge in: glm.fit(x = X, y = Y, weights = weights, start = start, etastart = etastart, ... 2: fitted probabilities numerically 0 or 1 occurred in: glm.fit(x = X, y = Y, weights = weights, start = start, etastart = etastart, ... ########################################################### For those cases for which I got the warning messages, shouldn't I rely on coefficents ? It looks like I can still extract coefficients from R outputs Are there any ways to avoid these warning messages ? or are these due to the problems with my data (e.g., perfect separation) Any help or advice would be appreciated Thank you TM ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
